2-amino-1H,2H,3H-pyrrolo[3,4-c]pyridine-1,3-dione, trifluoroacetic acid (CAS 1909325-33-2), molecular formula C7H5N3O2C2HF3O2 and molecular weight 277.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-amino-1H,2H,3H-pyrrolo[3,4-c]pyridine-1,3-dione, trifluoroacetic acid (C7H5N3O2C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
